Wayde is well known for pushing himself to the limit. After running the 400m in 43.48s in the World Championships in Beijing, he was unable to do a customary victory lap and instead had to be wheeled off the track and taken to the hospital.

Legend Michael Johnson thinks he’s just at the start of the race and that even greater feats are yet to come.

Many runners will be looking at the records they still hold nervously but when it comes to the Olympics a few will be breathing a sigh of relief; Wayde van Niekerk will only compete in the 400m in Rio.
